Disclosed herein is an electronic combination lock mainly characterized by miniature size and easy-to-use electronic identification access-gaining method that enables a vast variety and type of access codes for user setting and choice. Another battery operated electronic key unit, incorporated with programmed access code to provide as an alternative choice for locking, unlocking and backup power, can be used in conjunction with the electronic combination lock.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A miniature electronic lock comprising: a housing that includes a battery compartment; a shackle bar that fits into the housing; a movement sensor that is an acceleration or vibration sensor disposed within the housing and configured to detect a pattern of shaking of the miniature electronic lock; and an electronic system, protected by the housing, that includes memory storing a preprogrammed access code and that uses a microcontroller programmed by software to release the shackle bar upon the preprogrammed access code being received from a touch sensor and electronic display unit or from an electronic key, wherein the electronic system receives power from one or more batteries in the battery compartment, wherein the displacement sensor provides power saving activation for the electronic system by activating the electronic system in response to the detected pattern of shaking of the lock, and wherein the preprogrammed access code includes at least one shape and at least one color graphic.
2. A miniature electronic lock as in claim 1 , wherein the touch sensor and electronic display unit is a touch-screen liquid crystal display (LCD) that is turned off automatically by the electronic system after a short duration.
3. A miniature electronic lock as in claim 1 , wherein the touch sensor is a touch panel or a track-pad.
4. A miniature electronic lock as in claim 1 , wherein both a status of the miniature electronic combination lock and the preprogrammed access code remain in an initial state as stored in a memory for the electronic system regardless of whether the one or more batteries in the battery compartment are being removed or are completely discharged.
5. A miniature electronic lock as in claim 1 , wherein the electronic key serves as a proximity controller for the electronic system.
6. A miniature electronic lock as in claim 1 , further comprising a radio frequency receiver system to enable proximity access by the electronic key for input of the preprogrammed access code.
7. A miniature electronic lock as in claim 1 , wherein the electronic key includes a connector and the preprogrammed access code is read by the electronic system when the connector is inserted in a key hole in the housing that is configured to receive the connector.
8. A miniature electronic lock as in claim 1 , wherein the electronic key includes at least one battery and electronic circuitry to provide power to the electronic system.
9. A miniature electronic lock comprising: a housing that includes a battery compartment; a shackle bar that fits into the housing; a movement sensor that is an acceleration or vibration sensor disposed within the housing and configured to detect a pattern of shaking of the miniature electronic lock; a touch sensor and electronic display unit; a key hole in the housing that is configured to receive an electronic key; a radio frequency receiver system to enable proximity access by the electronic key; and an electronic system, protected by the housing, that includes memory storing a preprogrammed access code and that uses a microcontroller programmed by software to release the shackle bar upon the preprogrammed access code being received as input from either the touch sensor and electronic display or the electronic key, wherein the preprogrammed access code includes at least one shape and one color graphic, and wherein the displacement sensor provides power saving activation for the electronic system by activating the electronic system in response to the detected pattern of shaking of the lock.
10. A miniature electronic lock as in claim 9 , wherein the touch sensor and electronic display unit is a touch-screen liquid crystal display (LCD) that is turned off automatically by the electronic system after a short duration.
11. A miniature electronic lock as in claim 9 , wherein the touch sensor is a touch panel or a track-pad.
12. A miniature electronic lock as in claim 9 , wherein both a status of the miniature electronic combination lock and the preprogrammed access code remain in an initial state as stored in a memory for the electronic system regardless of whether the one or more batteries in the battery compartment are being removed or are completely discharged.
13. A miniature electronic lock as in claim 9 , wherein the electronic key serves as a proximity controller for the electronic system.
14. A miniature electronic lock as in claim 9 , wherein the electronic key includes a connector and the preprogrammed access code is read by the electronic system when the connector is inserted in the key hole.
15. A miniature electronic lock as in claim 9 , wherein the electronic key includes at least one battery and electronic circuitry to provide power to the electronic system.
16. A miniature electronic lock as in claim 9 , wherein the electronic key uses proximity access for input of the preprogrammed access code.
17. A miniature electronic lock comprising: a housing that includes a battery compartment; a shackle bar that fits into the housing; a movement sensor that is an acceleration or vibration sensor disposed within the housing and configured to detect a pattern of shaking of the miniature electronic lock; a radio frequency receiver system to enable proximity access by an electronic key; and an electronic system, protected by the housing, that includes memory storing a preprogrammed access code and that uses a microcontroller programmed by software to release the shackle bar upon the preprogrammed access code being received as input from the electronic key, wherein the electronic system receives power from one or more batteries in the battery compartment, wherein the displacement sensor provides power saving activation for the electronic system by activating the electronic system in response to the detected pattern of shaking of the lock, wherein the electronic key includes at least one battery and electronic circuitry to provide power to the electronic system, and wherein the preprogrammed access code includes at least one shape and one color graphic.
18. An electronic lock as in claim 17 , wherein the electronic key includes a connector and the preprogrammed access code is read by the electronic system when the connector is inserted in a key hole in the housing.
19. A miniature electronic lock as in claim 17 , wherein the electronic key uses proximity access for input of the preprogrammed access code.
20. A miniature electronic lock as in claim 17 , wherein the electronic key serves as a proximity controller for the electronic system.
